Moron- SPRING 'Harn foU'rrnn.

., Vania, have invented certain'newand useful improvements in MotonSpring lalair Cutters, ofV which the tion.` f

This invention relatesto certain new and useful improvements iin-hair Clippers andy has particular reference to the idea of providing a spring motor or other power means within the body ofv the` clipper for operating the cutting blades. e

The primary object ofthe invention resides in thel provision of a v hair clipper vwherein o-ne of theblades ofthe clipper con- `stitutes an integral part of the 'clipper body ward removable cover plate, and

or frame while-a shifta-ble o r reciprocating blade is operated by a springr motor contained within the body of the clipper. 1

Y A further object of the invention isto provide a spring motor operated vhair clipper wherein a band spring is associated with a relatively large gear for operat'inga pinion mounted upon a crank shaft, these inturn connected to a shiftable or reciprocating blade of the clipper.`

The invention further embodies in a. clipper including a spring motor for operation areciprocating blade, aclipperbody orcasingV having a removable coverto permit access tothe interior mechanism of the clipper for purposes of repairingor cleaning the same.k i f lilith theabove general objects in View and others that will appear as the naturey of the invention is better understood, the saineI consists of'thenovel form, combinationand arrangement of parts hereinafter more` 'fully'.

Referring more in ,detail to thel accompanying drawing thererislllustrated a hair yclipper comprising a body portion formed of bottoni wall 1 substantially circula-r asV Yindicated in Fig. 5 and having a. side extension 2 substantially rectangular in plan view with the eXtreme forward end free of the bottomwbeing. upwardlyinclined as shown tension 8; the portion ofv the'side wall eX tensions 6 .outwardly of the rectangular bot'- tonrwall'portion Q'having inwardly directed side y,flanges 7 shown' moreclearly in Figs. v1.,'. t and'G Aremovable cover plate 8 otfa y configurationsimilar to the bottom walll ismountedA upon the upperV ends of the side .walls and has a side extensionli) thereof ter-` ward ends of the flanges extending through the out away portions 12 with thecover plate shaft and the shift- Aable cutting blade, Y

providing an interlocking connection between the cover plate and clipper body. The cover 8 is maintained in position on the clipper body by hinge clips 13 having openings therein to receive lugs 14 carried by the cover S.

A spring motor driven gear is arranged within the clipper body and is associated with the arbor 15 ournaled in the bottom 1 and cover S as shown in Fig. 1, said arbor adjacent the lower end thereof having a ratchet wheel 1G secured thereto with a tensioned pawl 17 carried bythe bottom wall 1 associated with the pawl as shownV in Fig. 5. r)The spring driven gear embodies a disk portion 18 rotatable upon the arbor 15 and supported upon the blocks 19 carried by the bottom wall, an upstanding annular flange` 2() carried by the peripheral edge of the disk being provided with external gear teeth 21. A band spring 22 coiled around the arbor 15 within the gear fiange 20 has the inner end thereof secured as at 23 to the arbor while the outer end 24 is secured to the inner faceof the gear flange 20.

A perpendicular crank shaft'25 is journaled at itsopposite ends in the bottom wall 1 and cover 8 of the clipper body and has a pinion 26 fixed thereto in constant mesh with the gear teeth 21. A shiftable clipper blade 2T Vhaving a serrated cutting edge 28 is flatly mounted upon the inclined portion 3 of the bottom wall and is pivotally sup ported upon the pin 29 `adjacent the lower edge thereof, a link 30 being pivotally connected at one of' its yends as at 31 to theupper side edge of the blade 27 while the other end thereof is connected to the crank portion of Ythe shaftY y25.

4To place the spring 22 under tension, the thumb nut 32 removably secured to the upper end of the arbor 15 rotates the arbor, retrograde movement 'thereof being prevent ed b y the pawl and ratchet 17 and 16 shown in Fig. 5. To hold the gear 1S stationary while placing'the spring under tension, a strap hinged as at 34- to the outer face of the side wall 5 carries a lug 35 upon its inner face adapted lto project through an opening in the side wall for engagement withA the teeth 21 of the gear, the spring being wound to the desired tension by rotation of the arbor 15. When it is desiredto use the device for clipping hair, assuming that the spring `is under tension as above described, the strap 33 is moved outwardly of the side wall 5 of the clipper body to disengage the lug 35 from the gear teeth 21, the spring ro.-

tating the gear, and in turn the pinion 26 supported onthe crank shaft 25. The link rod connection between the crank shaft and the blade 27 will cause a pivotal reciproeat` mechanism in the side extension of the' clipper body while the body cover 8 also be removed by releasing the clips 13 to permit access to the band spring and gear wheel. The operation of the device is controlled by the hinge strap carrying the lug for engagement with the teeth 21 of the spring driven gear. Y y

While there is herein shown and described the preferred form of the present invention it is nevertheless to be understood that ininor changes may be made therein without departing from the spirit and scope thereof.

Y Whats is claimed as new is 1- f y A hair clipper of the type described coinprising a. substantially circular bodyportion, a side extension formed integrally therewith, the said extension being substantially rectangular in plan view withtheforward free end of the body upwardly in clined, inwardly directed flanges carried by the side walls of said extension, a cutter blade lformed integrally with the inclined bottoni of the extension, a cutter blade pivotally supported on the said inclined bottom, upstai'iding blocks carried by the bottom wall of the body portion, an arbor journaled in said body portion, a gear journaled on said arbor and supported on said block, a band spring associated with said gear and arbor, a crank shaft journaled in the casing, a pinion fixed to said crank shat'tin mesh with said gear, a link rod connection between the crank shaft and the pivotally mounted cutting blade, a removable cover for said casing, securing means for said cover, said means embodying hinged clips carried by said casing, the said clips having slots formed therein and lugs carried by said coverv adapted to engage the slots in said clips, and aA forwardly removable cover plate `carried by said extension, said platehaving ANDREW J.
